Calculate Standard Deviation in java

public class StandardDeviation {

    public static void main(String[] args) {
        double[] numArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
        double SD = calculateSD(numArray);

        System.out.format("Standard Deviation = %.6f", SD);
    }

    public static double calculateSD(double numArray[])
    {
        double sum = 0.0, standardDeviation = 0.0;
        int length = numArray.length;

        for(double num : numArray) {
            sum += num;
        }

        double mean = sum/length;

        for(double num: numArray) {
            standardDeviation += Math.pow(num - mean, 2);
        }

        return Math.sqrt(standardDeviation/length);
    }
}
